請問一下檔案大小的問題

要上傳的圖檔限制在寬500像素，而檔案必須超過50k，又只限制只能jpg檔，
本來檔案就不大，縮到500後就不足50k,
有辦法在這限制內讓檔案變大嗎？只要超過50k就好。

真是奇怪的限制, 大家都怕檔案太肥, 傳輸太佔頻寬, 存檔太佔容量.

這家卻反其道而行..

先去抓 FastStone Image Viewer..

用它看你的圖...

縮到 500px * 500px 後, 先適度銳化..

然後 save as , 選 jpg 時, 會有個 options ..

點進去, 我用的這張舉例照, 它的 new file size 將被存到 44.3K 多..

把 Quality 拉到 100%, 就變胖到 135K 了..

還要更胖, photometric 就給它選 CMYK, 暴肥到 224K .
